Having a sparatic issues with my remote voltage. Out of nowhere, I am having an issue with the amps/xm unit shutting off randomly. Turn the H/U off and it works again. Took out the DMM and found that Idle voltage is 12.4 and dips around 11.4 when the music is playing. Drove around for a few min and it did its thing again at which the voltage was around 5.5 and not sufficient to turn my amps on. I am running two amps, xm unit and SMALL low rpm fan on the remote circuit and have not had a problem for quite awhile...( I don't believe it is related to having too much stuff on the 12V remote) However....My H/U is over 3-4 years old Alpine 9827 Thinking it has gone through its …

soo i started my truck up at the bar,dude wanted to hear the system, cranked it up played a new cd i got. so my amp went into protect. i assume i clip at 26 vol on my head unit it goes to 30. i played it at 26. played the amp at what i would play it to do a demo with out distortion (by ear)and it went into protect! never had this problem AND i just put a xs 3400 under the hood it was at 14.5ish volts no drop....sooo like any ideas why this happened anything i should check or what not?

I'm a little bit confused about how to wire the RCA's. They have basically 6 sets of preamp outputs with some labeled mid, highs but also some sets labeled positive and negative. The manual isn't too detailed about using the pro setup except to connect all of them. I am going to be running tweets and mids up front and mids in the back. Plus a sub(which it has 2 pairs of outputs to as well for some reason). I will post some pix if necessary. Thanks for any help you guys can provide. I'm trying to get this done tomorrow as i will be working til 10 pm tonight.

Ok. So I put the zcon's and the 2500d in. Now when I set the gain using the dd1 till I can get ahold of my friend with the oscope, the voltage goes down to 12.5. I have a mechman 270, big 3 in 0 gauge, ran the pos and neg from front to rear batt in 0 gauge, installed fuse in front, fuse in rear, soldered all connections. Rear batt is a diehard platinum 31m marine agm with 205 reserve, but yet when I turn volume up to around 30 out of 35, amp goes into protect mode and volts drop to 12.5. (Radio was o scoped at 40hz and 1k hz and had no clipping evident)Even at 1500 rpm. Am I missing something or is the saz2500d drawing that much amperage? Also speaker wire was 14 gauge. A…

I was thinking... Deep cycles (ie. Yellow Top) are meant to discharge quite a bit over a long period of time, but starting batteries (ie. Red Top) are meant to discharge large amounts of current over a short period of time, like the starter. Now for our application, car audio, unless playing with the engine off for extended periods of time, wouldn't starting batteries be better? Music is quite dynamic, and as such, starting batteries would be better able to provide the bursts of current. Now I understand that purpose built batteries such as Kinetiks and Powermasters probably have high current in mind, but when using other batteries like Optimas, would a Red Top work bet…

I have spent an hour on google searching trying to find a neon light controller that will flash to the music using a rca cable so the neon flashes to the music and not people talking. I have seen them before but i cannot seem to locate one now that I wan't to get one.

i bought 2 group 31 batteries for my truck last year, they are now dead to the point that they can not start my truck in teh cold. i do not have lots of money to spend so i am looking for advice on whawt the best batteries are with out spending 700 on stingers. I have a cummins turbo deisel that requires about 220A for 30 seconds in cold weather to heat the air intake, it pulls 750-950A from the starter for about 15 seconds of cranking when cold. i have 1500W of amps for mids/highs and a 2500.1 for my sub. my alt can handle them just fine while running. what 2 batteries should i get? should i go agm for starting or stick wtih liquid acid?

I have an ssa icon 15 dual 2 ohm and I am looking for a new amp to run it. These are the two I have found ... http://cgi.ebay.com/NEW-SOUNDSTREAM-...QQcmdZViewItem http://cgi.ebay.com/NEW-HIFONICS-TXI...QQcmdZViewItem any suggestions would be helpful my budget is about $250

I was just wondering what's the biggest wires you guys can use for the sub to the amp and the wires for wiring the dvc terminals together (if you have dvc) the biggest i've seen were 8g, is that the biggest it can go?, personally i never tried this so i wouldn't know and im planning to upgrade my wires sooooooooooon

just wondering what rca cables people recommend when it comes to price and performance?

im so confused! so is a bass remote bad to use if you want ur subwoofer to be "quiet?" i know i know Who would ever want their sub to be quiet but im just wondering. ive heard it can hurt the amp/sub or it cant, i neeed answers!!

Ok, so yesterday I was warming the car up for an oil change and started beating on the system a bit. I noticed one woofer not moving quite as much as the other. So today I took all the speaker wire out of the amps (2 bc3500's strapped) and each woofer is reading 4 ohms??? It's supposed to be wired to 1 ohm per woofer 2 ohm strapped. I don't know what I did wrong. I'm not sure if there is a different way to check impedence if the amps are strapped.? I notices the master amp gets slightly warm and the slave is cold. I need some advice as I'm gettign frazzled. The woofers are 2 fi btl 15's Dual 2's I put a camera inside the box to make sure no wires came loose but everything…

Well I just got back from picking up this earthquake amp. In a little rough shape but it is a ph1000w 2 channel. Any input on this?

Just installed my cda-9886 and it plays the radio but on cd's it shows that its playing but no sound. Same with ipod. I'm thinking it has to do with it possibly beig a faulty cd player... which is ganna piss me off. Any ideas?

So I've been looking around for a while and am looking for a new head unit. I was looking for one with: - USB connection to charge and control I Pod through head unit. - Play's CD's well. - AM/FM radio with presets. - 4v RCA pre-outs My price limit is $300. And what I've been looking at are: - Pioneer DEH-P7200HD - Alpine CDA-9886 - Eclipse CD7200 mkII Have you used any of these head units, & which one do you think I should get? Thank you, And I'm up for any other suggestions.

Is the Deka decent at start vehicles? My dad offered to put $200 to a new battery for me, and I have heard nothing but good things about the Deka's. Anyone have any major problems? And how does it compare to the Optima Yellow Top?

Ok so I have 2 fi ssd 12"s and a sundown saz-1500d, my problem is if I turn it up past 32 on my head unit, my amp goes into protection and it sounds like one of the subs "pops" any help would be awosme

I'm going to buy my gf some components because the speakers in her car sound really crappy and bugs the hell out of me. I need some suggestions on some good sounding 4 channel amplifiers that can be purchased for less than 300. Can either be a authorized dealer or ebay. Any help would be appreciated.

I am running an saz 1500d and 100.4 and I have a stock 145 amp alt. I already have a red top optima battery in the oem spot but I need another battery for the back can I use another red top or should I get the yellowtop? will a red in the front and yellow in the back be ok because they are different? Noobie question

I'm about to order an XS Power D925 for the second battery in my suv. I have a bigger battery upfront i got from o'reilly's. It's not a deep cell but it's about the biggest I could get with out spending a ton cuz i was on a budget. Now my question is should i buy a different battery for upfront? My goals are just to get my voltage to stay at a constant voltage. My amp draws around 1500 rms and when i upgrade will probably be in the 1700-2000 rms range. What do you guys think?

ok noob here and i was thinking i should get a yellow top under the hood, do the big 3, and get a kinetic hc2000. now my question is do i neeed the second batt? i heard that a second batt isnt neccesary if you wont play music with your car off. the yellow top under the hood and big 3 are going to be done for sure though. oh and one more question how many ft of 1/0 wire would i need to do the big 3. i have a 00' honda accord coupe. alternator will be done soon need help on that too but dont want to spend more than 400 on one?

Hey guys quick question: I understand this: Voltage of the output = sqrt(RMS Power X impedance of the speaker) Example Say the amp provides 100WRMS into a 4 ohm speaker: Voltage = sqrt(100W X 4 ohms) Voltage = sqrt(400W*ohms) Voltage = 20V So I have a 1500W amp and two dual 1 SSD12s. Would it be? Voltage = sqrt(1500W x 1 ohm) Voltage = sqrt(1500W*ohms) Voltage = 38.7V Should I use 30HZ, 50HZ, or 100HZ tone?

What's the deal with them? When will they be available? Got any specs?

Ok so i noticed yesterday that my radio would cut out at high volume so i went to the truck looked at the wires and erething seemed coo, I hop back in and it wrlks so i start driving and it does it again... So i justy turn it off and say i'll deal wt it later, so today i get the test light out and go under the hood, and DAAAMMM, my fuse holder was melted and it had started to melt into my finder well.. But the fuse never blew, and basiccly it was only on the side before the fuse. IT was molting i mean the gold was melted off it looked bad i would take pics but its uggly.. Why did this happen? I've seen it happen on amplifiers wt plastic coatings around the batt terminal,…
